Include in Response the specific phones used to view mailings

I was wondering if there are plans to give more detail to the type of devices that are opening mailings? In particular I am wondering about phone types. What percentage of iPhone 3s 4s and 5s or Samsung S2, S3, S4 and S5?

I've been testing some mailings in different phones and although newer phones display the mailings really well older ones do not on some older phones the emails are practically unreadable.

Hi there! We discussed this during the design phase of the new Response page and decided that the ever-changing landscape of the mobile market is too much of a beast to try to display and keep current with the exact mobile devices. Great timing today, too, since Apple just introduced two more iPhones. :)

Let me know if you have any questions about this! I'm going to tweak this subject line a bit for anyone searching for this, too.
